Update frequency of blockchain token
This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
Art Instry
ascribe allows artists to declare ownership, issue numbered and limited edition works, and aim at any type of artwork in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
legal instry
bitproof is the most advanced of many document time stamp applications emerging in recent years, which will make the traditional notarization method a thing of the past. Bitproof offers more services than versions including blocksgin and originstaemp, including one for intellectual property.

development instry
colu is the first enterprise to allow other enterprises to issue digital assets. They can "token" all kinds of assets and make a profound impact on many people. Although the bitcoin wallet couperparty also allows the issuance of simple tokens and transactions among other wallet holders, the tokens of colu can be set with various states and types, and can be detached from or returned to the system. When the data stored on the blockchain is too large, the data can be stored on the BitTorrent network
network mutual aid instry
concentric mutual aid is the first blockchain network mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, the defects of traditional network mutual aid mode can be eliminated, and a new open and transparent network mutual aid platform can be established.
Pure blockchain technology can also be applied in non-financial fields. Here are some examples of blockchain technology application:
-
cross center sharing of provident fund blacklist
ant financial blockchain and Huaxin Yong build "cloud platform of joint dishonesty punishment and deposit proof", Hainan province takes the lead in sharing the black list and deposit certificate of provident fund across centers and regions through the platform -
business service blockchain platform
the platform uses blockchain technology to open the service mode of "all-weather, zero meeting, one click" and applicants can apply for business license through the "blockchain + AI" platform, which takes only one and a half hours -

there are many areas where blockchain technology can be applied, and it does not have to be related to digital currency. Cryptography focuses on blockchain information< br />
the fourth category is the asset token blockchain project. Asset token refers to linking blockchain assets to physical assets such as gold and US dollars. It is the blockchain mapping of physical assets. At present, there are no more than 10 varieties. The typical representative is usdt against US dollars, digix Dao against gold, digix. Each token represents 1 gram of Gold Certified by London Bullion Market Association
asset token has the advantages of convenient transaction and storage. First of all, asset token is more convenient for transaction. Because blockchain assets can be split, it has better liquidity. For example, at present, real estate needs to be transferred as a whole. If the real estate can be token, it can be split and purchased, which is more convenient for transaction
secondly, the token of physical assets is more concive to custody. Gold is easy to wear out and cause losses in physical transactions. However, after the token of physical assets, there is no need for physical transfer, which is more concive to the custody of physical assets.

the barn app makes use of the characteristics of the blockchain technology to trace the whole process of goods through the blockchain technology, applies the blockchain technology to the user's shopping, sharing, browsing and other scenes, and presents it to the user through the token (negotiable digital proof of rights and interests), in which each participant can share and use the data as needed, To achieve high reliability of data trading market, low-cost transactions and multi win<
